I am not sure. There are two possibilities one isPedro Regalado Leal de Escamilla are Capitan Antonio Leal (born 1678, died 1756) and Manuela Guerra (born 1683). The Paternal grandparents were Capitan Antonio Leal de Leon (born about 1645 in Cadereyta and died March 6, 1756. and Juana Josepha Gonzalez (born 1649 died 1689). Juana' is sometimes listed as Juana Gonzalez Hidalgo. Her parents were Capitan Bernabe Gonzalez Hidalgo and Leonor Gutierrez (born 1618). Manuela's parents are Capitan Ignacio Guerra Canamar (born 1637 died 1702) and Catarina Fernandez de Tijerina born about 1656. She was married about August 4, 1676 in Monterrey.
The other possibility is Francisco Perez de Escamilla born 1670 and Isabel Gonzalez Hidalgo born 1676. Francisco's parents are Francisco Escamilla born 1630 died 1672 and Leonor de Trevino aka Leonro de Ayala born about 1630 died Octrober 3, 1696 Monterrey Mexico. Isabel's parents are Bernabe Gonzalez Hidalgo (same as above but with a different wife) and Josepha de Trevino. Hope this helps
